Would the war against Japan end faster if MacArthur served in a different theater?
Short answerNot by much; logistics, shipbuilding, subordinate commands, and Nimitz's advances mattered more to the overall pace.
NotesMoving MacArthur to another theatre is judged unlikely to change the war's duration very much. Logistics and shipbuilding set the pace of operations against Japan. Subordinate commanders are also given more weight than MacArthur personally in determining what his forces could accomplish. Nimitz's command supplied much of the pressure on Japan and secured stepping stones for the strategic bombing campaign.
